  Fig. 3. Transcripts of α-neurexins are expressed in Xenopus oocytes. Ovarian tissue consisting of connective tissue, follicle cells and oocytes at different stages of development was subject to wholemount in situ hybridisation using probes specific for each of the neurexin transcripts. (A) An nrxn I specific probe identifies transcripts equally distributed through small, early stage oocytes (yellow arrows). At later stages, the nrxn Iα transcript is localised to a crescent within the large oocyte (red arrows). Transcripts were not detected in cells other than oocytes. (B,C) Nrxn II (B) and nrxn III (C) transcripts were found in all stages of oocyte. At the later stages, in the large oocyte, the signal is less intense probably due to the dilution of the mRNA in the larger cytoplasmic volume. There was no evidence for localisation of these transcripts and neither were they detected in cells other than oocytes. Right-hand-side panels: negative controls, hybridised with corresponding sense neurexin cRNA probes

  Fig.4. Expression of α-neurexins is predominantly in neural tissue in the tailbud embryo. (A,B) In situ hybridisation with a nrxn Iα probe showing whole embryo (A) and an anterior neural section (B). Nrxn I is found in cells along the length of the CNS but with a distinct gap at the midbrain-hindbrain boundary. Sections show expression in the dorsolateral neural tube and within the eye. (C,D) Embryos hybridised with a nrxn IIα-specific probe show a similar pattern of staining to that seen with nrxn I. (E,F) Embryos hybridised with a nrxn IIIα-specific probe show much more restricted expression in the CNS and in section show ventrolateral and eye expression in the anterior CNS (arrows).
